yes, I did. I am aware of need_module() and have_module() being almost
the same thing. Now please have a look at Apache::ModSSL/t/1is_https.t
and TEST.PL:

TEST.PL:
-----------------------------------------------------------------------------------------------
...
my $I=Apache::TestRunPerl->new;

my @[EMAIL PROTECTED];                  # save it

$I->run(@ARGV);
system "cp t/conf/apache_test_config.pm t/conf/apache_test_config.pm1";

Apache::TestConfig::autoconfig_skip_module_add('mod_ssl.c');

$I->refresh;

$I->run(@argv);
system "cp t/conf/apache_test_config.pm t/conf/apache_test_config.pm2";
-----------------------------------------------------------------------------------------------

For debugging I am duplicating the generated apache_test_config.pm files.
They do differ. The 2nd one lacks the "LoadModule ssl_module" as expected.

  open my $f, "t/conf/httpd.conf" or die "ERROR: Cannot read t/conf/httpd.conf:

  return grep(/^\s*LoadModule\s+ssl_module\b/, <$f>) ? 1 : 0;
}
...
#if( have_module('ssl') ) {
if( ssl_loaded ) {
  plan tests => 2;

  ok t_cmp( test( 'default', 'is_https' ), "HAVE_SSL=1 is_https: 0\n", "no ssl" 
);
  ok t_cmp( test( 'SSL', 'is_https' ), "HAVE_SSL=1 is_https: 1\n", "ssl" );
} else {
  plan tests => 1;

  ok t_cmp( test( 'default', 'is_https' ), "HAVE_SSL= is_https: UNDEF\n", "no 
ssl" );
}
-----------------------------------------------------------------------------------------------

My ssl_loaded() function distinguishes between the 2 cases, have_module('ssl')
does not. With have_module() always the 1st case is entered.

Here is an excerpt of Apache::Test:

sub need_module {
...
   for (@modules) {
...
            next if $cfg->{modules}->{$mod};
            if (exists $cfg->{cmodules_disabled}->{$mod}) {
                push @reasons, $cfg->{cmodules_disabled}->{$mod};
                next;
            }
...
    }
...
}

Since my Apache::TestConfig in both cases contains "mod_ssl.c" in
$cfg->{modules} the test will succeed. The
"Apache::TestConfig::autoconfig_skip_module_add('mod_ssl.c');"
is disregarded while generating this hash.
